CAR-GOUPLlNG.

SPECIFICATION forming part of Letters Patent No.318,958, dated June 2 1885.

Applicatirn filed June 7,1883. (X model.)

To all whom, it may concern.-

Be it known that I, JEssE Roenns CooL- BAUGH, a citizen of the United States, residing at W'ysox, in the county of Bradford and State of Pennsylvania, administrator of the esmm of :MATTHEW CAMPBELL CANNAN, late of Ulster, county and State aforesaid, deceased, have applied for Letters Patent fora certain new and useful invention invented by the IO above-named MATTHEW CAMPBELL CANNAN, called the Canaan Car-Coupler, for ooupling and uncoupling railroad-cars, of which the following is a specification.

This invention relates to an improvement in 1 car-couplers; and the object of the invention is to provide a good and sufficient car-coupling that may be operated from either side or top of cars, thereby saving time, and also avoiding the necessity of the operator going between the cars in coupling and uncoupling the same. These objects are attained bythe mechanism illustrated in the accompanying drawings, in which similar letters refer to similar parts throughout the several views.

2 Figure 1 is a perspective view of the drawbar and coupling devices. Fig. 2 is a vertical longitudinal section, and Fig. 3is a hori' zontal section thereof.

A represents the end of the car, and F B 0 c the levers for coupling and uncoupling from the sides or top of the car.

F is an elbow-lever pivoted at its elbow to an extension of the sliding box E by bolt G, which slides in the slot D in the end of the 5 car. The lower end of lever F is pivoted to the cross-lever B,which extends to either side of car. The toggle-lever O is pivoted to the cross-lever by bolt f, and its lower end is pivoted upon the end of the car by bolt b.

E represents asliding box,whioh carries the couplingpin K upward through link J, to couple the cars and downward to uncouple, and is operated by the levers F B G.

L represents a metal draw-bar, in one piece, having square opening a a to receive link-follower U U, with its spiral spring V, which operates it. The opening also receives link J, with its collar 0. The draw-bar has a flaring mouth sufficient to receive links from cars of ditferent heights and widths, and also has an opening in opposite end for bolt M to screw in; also, a round opening, Z, extending from end of bolt M to square opeuingn, for linlcfollower U to operate in.

J isa coupling-link with wedge-shaped rear 5 5 end resting in socket of link-follower U, as shown in Figs. 2 and 3, the sides of said link tapering each way from link-collar O, and the corners being slightly rounded at each end.

K represents an angular coupling-pin attached horizontally movable to the bottom of sliding box IE, and then passes vertically up through draw-bar L, and may be made of solid round metal bent at a right angle, or of bars simply joined together at the angle, which will facilitate the removal and replacing of pins in case of breakage.

H represents the elongated box in which draw-bar L plays back and forth, being acted upon by spiral spring T, placed between washers NN,said washers sliding in rabbets t tin rear end of box H. The bottom of car, together with timbers and iron plates that are used around many of the draw-bars in present use, may take the place of box H.

NN are square cornered washers operating in rabbeis it.

T is a spiral spring between washers N N in rabbets i t, and is for the purpose of buffer and draw spring by means of bolt M passing through washer N, spiral spring T, and other washer, N, and then screwinginto rearv end of draw'bar L.

Mis a bolt that screws into rear end of drawbar L and takes the draft-strain. 8 5

U U represent a link-follower with squareshaped outer end, having therein an oblong socket, in which rests the inner end of link J.

V is a spiral spring acting upon link-follower for the purpose of-keeping link J at all 3 times in place to enter of itself and without assistance the mouth of draw-barL on opposite car.

O is a square-cornered collar around link J near its inner end, and can be made of halfround iron or any metal of similar shape best adapted for the use it serves, the flat side being toward the link.

R is a pin running laterally through collar 0 and link J, said link being suspended thereon, and it is by means of link-follower U U and collar 0 and pin R, acted upon by spiral spring of draw-bar that the end of link is movable up or down to one side or the other, as is necessary in coupling cars of unequal heights and widths, and link J may take the position of J when attached to a similar draw-head on alower car; and as each and every draw-head has its own link the above arrangement allows the link to pass over or under the opposite link, when one or both links may be coupled by pin or bar K in opposite draw-head, thereby making a double or single link-coupling, as necessity may require.

r is a pin passing through top of draw-head L, thence through opening in link J, close in front of collar 0, and then into bottom of draw.- head L. It is the inner bearing-bolt of link J, and aids in keeping said linksuspended in place for use, as may be seen in Fig. 2, and is only moved in case of removing and replac: ing link for repairs.

P P are stationary pins in end of box-car, on which lever B rests and operates upon horizontally across end of car; and Bis the lever by which the operator raises or lowers coupling-pin when standing at either side of car. The coupling is done from top of car by lifting, and at same time throwing lever F over to the right, and uncoupling by throwing in opposite direction. The lever B has three shoulders or offsets on the bottom, and, as shown in Fig. 1, two of these rest against pins P P, and said pins hold the levers when pin K is dropped down to its proper place when uncoupled, and the other shoulder rests against pin P at the right, and this pin keeps it there when coupling-pin K is raised to place in coupling by levers being thrown to that side; and in case it is found that this pin P at the right is not sufficient at all times to hold the levers in place when cars are coupled, spirals or any. springs answering a like purpose may be placed under the top of the opening of sliding box E and directly over draw-bar L, which will not only serve as a lock in keeping sliding box E up when coupled, but would assist in raising the same when operated. The levers F B O are more especially calculated for freight-cars, yet may be used on many others, and on some cars-such as flats-1 where the levers F B C and extension on sliding box E arein the way, said box may be moved up and down by simply running levers from each side of car, attaching them to sliding box IE, and pinning them to car at a proper leverage distance from box E, thereby doing away with levers F B C and extension on sliding box IE.

I am aware that prior to this invention carcouplers have been made using washers and spiral springs in and about their construction similar to these. I therefore do not claim the whole, broadly, as described in the specification, and shown in the drawings; but

What I do claim in this invention, and do sire to secure by Letters Patent, is

1. In a car-coupling, the combination of the upright lever, the cross -levers pivoted together, and the vertically-sliding box carrying the coupling-pin,whereby the coupling is effected from the top of the car, or from either side by operating one of the levers, substantially as described.

2. In a car-coupling, the combination of the vertically-sliding box provided with a coup ling-pin, the side levers, and the lever connecting the said side levers to the sliding box, substautially as and for the purpose described.

3. ,In a car-coupling, the vertically-sliding .box IE, sliding over the draw-head, and into which the draw-bar passes, and provided with a coupling-pin, in: combination with the toggle-jointed levers for operating the same, substantially as described. I

4;, In a car-coupling, the combinatiomwith the draw-head provided with the collarO, of the link pivoted to said collar, substantially as and for the purpose described.

5. The combination, with the draw-head,

of an open linki secured to said draw-head, the collar, to which said link is pivoted, the linkfollower provided with a socket to receive the end of the link, and the spring V, substantially as and for the purpose described. 6. In a car-coupling, the combinatiomwith the vertically-sliding box, the side levers piv-t oted together, and provided with the shoulders or offsets, in combination with pins P, whereby the levers and the coupling-pin are held in their proper place when the car is coupled or uncoupled, substantially as described.

7. A car-coupling comprising, incombinaiion, the draw-head, the box provided with a coupling-pin sliding over and above the drawhead, the top and'side levers for operating said sliding box, the link pivoted within and permanently secured to the drawhead, the

drawbar provided with the socketed head,

and the springs in connection with the drawbar, substantially as described.
